Kardashian was outspoken in her support of Obama during his 2012 presidential run, and even “wanted to be a ‘surrogate’ for the campaign,” the source explains, but “they wanted nothing to do with her. She was not the young, cool, image they wanted to portray at all. Even though she kept asking, the campaign would never let her do anything in an official capacity.”

“Kim is political poison,” the source continues. “Having her involved in a political event or with a candidate is the last thing people who are serious about getting elected want.”

Two years later, that’s still true. Kardashian made an appearance at Independent congressional candidate Marianne Williamson’s fundraiser in L.A. on Tuesday night, but RadarOnline.com has exclusively learned that the 33-year-old sex tape star — and her plunging neckline — failed to impress the politicos present.

More popular was Katy Perry, who also attended the event and was front and center throughout Obama’s presidential run.

“Katy is on a different level than Kim,” the insider explains. “Everybody loves Katy. Kim is so controversial and it’s just too risky for any candidate to have her involved.”

Does Kim Kardashian’s endorsement of a candidate make you want to vote for them?
